This has so terrified John that he has opted not to go back to his house but instead stay at a Bed and Breakfast.  Brendan Coyle is completely believable as this man who has seen a ghost.  He is shaken to his core.  Rory Keenan actively listens with a repetitive "I know", his way of reassuring the client and mirroring the number of times John says, "You know."   In this first scene we learn only about John's issues and Ian's professional side.
